Move router far from hifi components?

I just finished reading Hans Beekhuyzen's Kindle book on file based audio. This is what he said about where your router should go.


"Like cell phones, Wi-Fi uses radio frequencies that might cause interference in your stereo. Try to keep the Wi-Fi access point as far as possible from the hifiequipment and always use well shielded audio, power and network cables on your hifi. If Wi-Fi is your only choice, you’d rather hope you’re in an area that has little Wi-Fi traffic."

i don't think I have heard about this before and was wondering if this really makes a difference. I'm tempted to move my router and modem to another room to test but wanted to poll everyone to see if they have done this.
